The British-born Cruz commands the list a week after B.o.B became the 12th lead solo male to reign with a first entry. While eight male rookies ruled between the chart's inception in 1992 through 2008, Cruz is the fifth to reign since October, when Jay Sean reached the summit with "Down." Jason DeRulo and Iyaz followed Sean to No. 1 last year.

(With 10,709 plays logged in the Pop Songs chart's tracking week (May 10-16) on 132 stations (an average of 81 plays per station), according to Nielsen BDS, "Break Your Heart" is the most-played title in a week by a male singer in the survey's 17-year history).

Here is a look at the 13 lead male soloists to top Pop Songs with their first charted titles:

Is the recent upswing in new male artists ruling Pop Songs a coincidence? Or, are mainstream top 40 programmers more actively seeking a balance between male and female vocals in the upper reaches of their playlists?

WHTG (Hit 106)/Monmouth, New Jersey program director/music director Matt Knight cites an "abundance of good songs by male artists right now."

"Pop is a cyclical format, not just by genre, but in terms of male and female artists, as well. 2009 saw Lady Gaga, Katy Perry, Ke$ha and the resurgence of Britney Spears. Now, there's a great selection of male artists such as Cruz, Usher and B.o.B," says Knight, who anoints "B.o.B Presents: the Adventures of Bobby Ray" his "favorite hip-hop album of the last five years."

"I believe that a good song is just that, regardless of whether a male or female singer is performing it."

Zapoleon Media Strategies president and Hitpredictor partner Guy Zapoleon likewise theorizes that Cruz's new leader continues a longstanding pattern in which pop radio listeners will always seek one of the format's hallmarks: variety.

"By their very nature, tastes of the public swing like a pendulum from one side to the other. People always want what they aren't hearing," says Zapoleon, who, among his storied radio career, is credited for reviving UB40's No. 34 1984 Hot 100 hit "Red Red Wine" while at KZZP/Phoenix in 1988; strong listener reaction to airplay on the station spurred A&M Records to re-release the song, resulting in it reaching No. 1 that October.

"(Listeners) want variety, and there has been such a flood of incredible music from great female artists that the pendulum was destined to swing back to some great music from male artists.

Concurring with Knight that a song's strength is the ultimate key to programmer acceptance, Zapoleon says that Cruz's hit easily passes the test.

"'Break Your Heart' is one of the best and most memorable songs of the past couple of years."
